1. The problem statement, all variables and given/known data A spaceship moves away from the earth at a speed v, and fires a shuttle craft in the forward direction at a speed v relative to the ship. The pilot of the shuttle craft forward launches a probe at a speed v relative to the shuttle craft. Detrmine: a) the speed of the shuttle craft relative to Earth b) the speed of the probe relative to Earth 3. The attempt at a solution Im just completely confused with this question, do i have to use Lorentz transformations?? but if so, how do i compute an answer?? plz can someone help, completely lost with this one.
